able others skilled in the art to which it pertains to make and use the same.

My invention relates to improvements in apparatus for attaching covers to pamphlets, in which the pamphlets are placed in quantity upon a table with the back downward, and moved by an endless belt to feed-rollers that discharge the pamphlets, one at a time, to the clamping device,wherethecoversare attached, the back of the pamphlet, in its passage to the clamp, passing over a paste or gluing roller. Suitable mechanism is provided for opening and closing the clamp at the proper time, and for moistening and breakingthecoversinto the clamp, the object being to provide an automatic machine for expeditiously performing this class of work.

With this object in view my invention consists in certain features of construction and combination of parts hereinafter described, and pointedout in the claims.

In the accompanying drawings, Figure 1 is a view in perspective of my improved apparatus. Fig. 2 is an elevation in transverse section on the line ofw as, Fig. 4. Fig. 3 is an elevation in transverse section on theline of y y. Fig. 4. Fig. 4 is a plan view with the table top or cover removed. Fig. 5 is a view in perspective of the block and spindle k and 70. Fig. 6 is an elevation in transverse section through the central portion of the breaker. Fig. 7 is a view in perspective, in detail, of a friction-clutch, hereinafter more fully described. Fig. 8 is a view in perspective, in detail, of a self-righting stop. Figs. 9 and 10 are enlarged views of the bar J and attachments, the former being a plan, partly in section, and the latter a side elevation.

A represents a table, to the frame-work of which are attached suitable boxes,in which are respectively journaled the driving -shaft B and the shaft 0, the two shafts being intergeared, as shown in the perspective, The

(No model.)

driving-shaft has a driving-pulley, B, mounted thereon, and made to drive the shaft by means of an ordinary clutch, B, by operating which the machine is started or stopped. On the shaft B is secured the cam-disk b and the adjustable cam 12. thereon bevel-gears for driving the upright rollers, D and E, that are located directly above the shaft 0. These gears, one set of which are shown at D, Fig. 3, are arranged to drive the said rollers in the same direction. On the shaft 0, at the rear of the said gears, is mounted the cam c. Opposite the roller E is the roller F, that is journaled in a sliding frame, F, that rests in a groove of the table, and may be adjusted toward or from the roller The shaft 0 has mounted E by means of elongated holes f, through which 7 the boltsf pass that secure the frame F to the table.

G is an endless belt, preferably of metal, the upper part of which operates in a groove, a, in the upper face of the table. This belt is provided with a series of holes, 9, that are preferably made diamond-shaped, as shown. The belt passes over the pulley H, the spindle of which is journaled in suitable brackets, h, attached on the outside of the table,and passes over the drivingpulley I, the latter being provided with sprockets i to engage the holes 9. The pulley I has a flange, I, that is embraced by the head of the bar J, the latter fitting the flange easily, so as to slide thereon when in a radial position relative to the flange,but when tilted out of such radial position would cramp and move onlywith the flange.

A spring, j, is attached to the bar near the pulley to depress this end of the bar. A thumb-screw, J, passes through a threaded hole in the bar near the free end thereof, and the end of the screw engages a stop, 9' and limits the depression of the free end of the bar. The cam c engages and elevates the end of the bar more or less, according to the adjustment of the thumb-screw J. As the spring j always holds the head of the lever in a crampedposition on the flange, the lifting of the lever by the cam turns the sprocket-wheel I and moves the belt in the direction of the arrow. As the cam moves from under the bar, of course the free end of the latter will fall by gravity until the thumb-screw J strikes the stop 9' and simultaneously therewith the spring 7', and the gravity of the head of the bar will cause this end to descend until it cramps on the flange of the pulley, and in such cramped position there will be no lost motion between the lever and flange when the bar is again elevated by the cam.

A broad block, K, usually of wood, is set over the belt at some distance from the roller D, and has attached tothe bottom ofthe block a plate, K, provided with depending lips that embrace the edges of the belt, by means of which the block is held in position with its face at right angles to the line of the belt. The block is detachably secured to the belt by means of a vertical spindle, k, that passes through the center of the block, the head of the spindle 7c being made diamond shaped to correspond with the holes in the belt, and by passing the head through a hole and turning it crosswise (see dotted lines, Fig. 5) the block is secured and made to move with the belt toward the roller D. The spindle hasathumb piece, k", for turning the spindle, and the lower portion of the thumb-piece next the block is in the form of an annular laterally-projecting flange with a notch in the periphery thereof. A spring, k, is secured to the block, and the free end of the spring is arranged to en gage the notch k of the thumb-piece and hold the same from turning when the head of the bolt is in position crosswise of a hole, 9, for securing the parts.

A quantity of pamphlets with the stitched edges or backs in position downward are placed on the table over the beltand between the block K and the roller .D,with the ends of the pamphlets abutting against the guide T, and are moved toward the roller by the intermittent movement of the belt. The roller D, near the bottom end thereof, has a series of laterally-projecting points, (1, arranged circumferentially around the roller, so that, when a pamphlet is pressed against, the roller engages the same and discharges the pamphlet between the rollers E and F, that are adjusted a suitable distance apart, according to the thickness of the pamphlet.

O is a paste-roller journaled in suitable boxes depending from the table. The upper face of the roller extends slightly above the table-top in such position that the back ofthe pamphlet rests on and revolves the paste-rolh er. The lowerpart of the paste-roller extends into the paste-box O, and as the roller revolves it carries up paste and distributes it along the back of the pamphlet. Of course glue may be used instead of paste. The feed rollers E and F discharge the pamphlets into the clamping device between the jaws M and M. Light elastic fingers c are adjnstably secured to the frame F, and are made to embrace the upper portion of the pamphlet to hold the leaves thereof from spreading after leaving the. rollers. Thejaw M is stationary. The movable jaw M. is forced in the direction of thejaw M by the cam b as thelatter engages the frictionroller m, that is connected with the movable jaw, and is moved back or opened by the springs m that are attached to the table and respectively to either end of the jaw. Athin metal plate, at, forms the bottom of the clamp, and a gasjet located under the plate or other means are employed for heating the same.

The cam b is made to embrace a flattened portion of the shalt B, and may be adjusted radially on the shaft to give the cam more or less throw, so as to close the clamp more or less, according to the thickness of the pamphlets. Suitable setscrews are provided for adjusting and holding the cam, as shown more clearly in Fig. 2.

While thejaws of the clamp are distended, the cover for the pamphlet is placed in position over the clamp. Suitable mechanism is provided for pressing down or breaking the cover into the clamp, and at the same time wetting this portion of the cover, and is as follows: The breaking device consists of an oblong metal box or container, L, with a depending narrow part, L, that is made to pass down between the distended jaws of the clamps. The part L is open at the bottom, and has an adjustable side, Z, hinged at the top to the ends of the box, and at least in one of the hinges. The pivot thereof extends outside the box, and is threaded and provided with a thumb-nut, Z, by means of which the hinge may be tightened to hold the part l in the desired position, with the bottom thereofseparated more orless from the stationary side. The space between the adjustable and stationary sides of the part L is packed from the bottom with sponge or other suitable material for holding water, and should protrude slightly below the edges of the box. The box L is provided on top with a suitable opening, L", for supplying water. The box is rigidly secured to the arm N, that in turn is mounted on the rock-shaft N. The outer end of the shaft has a rock-arm, n, to which is pivoted the push-bar P. The free end of this bar is supported bya rock-arm, 1), that is pivoted to the bar and to the frame of the table at p. The free end of the push-bar is in position to engage the periphery of the cam-disk b, by which engagement the bar is forced back endwise, by means of which the rock-shaft N, the arm N, and the box L are actuated, and the latter israised some distance and out of the way of the forthcoming pamphlet. As the notch in the disk 1) comes in position for the push-bar to enter the same, the gravity of the box L causes it to descend between the jaws of the clamp. wetting the cover and breaking it down into the clamp and pressing the central part of the cover upon the heated plate m. The breaking device rests but a moment in its depressed position, and is then quickly elevated, directly after which a pamphlet is discharged from the feedrolls into the clamp, and rests with its back upon the cover. Next the clamp is closed upon the pamphlet, pressing the cover firmly to its place so far as the jaws extend upward- IIS tion of the cover to set the paste or glue.

} the disk.

a distance usually of about half an inch, more or less. The clamp remains closed but a moment, but long enough in the heated condi- As thejaws open, the pamphlet is removed, another cover is placedin position, and the operation repeated.

The pamphlets are discharged with such velocity from the feed-rolls that the rear end would usually move two or three inches beyond the rolls. It is therefore necessary to have a stop to limittheir movement. The device employed for this purpose is more clearly shown in Fig. 8, and consists of a plate, R, with a slot, B, through which a thumb-screw passes that secures the plate on top of the jaw M. The plate is provided with an upright arm, R", to which is pivoted the segmental disk r, the plane of the disk being at right angles to the line of the plate B. One side of the plate is set about flush with theinner edge of the jaw M. (See Fig. 4.)

The flattened side ofthe disk is of course the lightside,andthe disk by its own gravity,\vhen left free, assumes the position shown in Fig. 8, in which the disk extends more or less beyond the edge of the jaw M and over the trough between the jaws, in which position it engages the forward end of the pamphlet and forms a stop for the same. When the brake L descends, it strikes this projecting part of the disk r and turns it down, so that the flat side of the disk is vertical, in which position there is room for the part L to pass by the side of WVhen the part Lis elevated, the disk again returns to its normal position, as shown in Fig. 8, and again acts as a stop to the pamphlet. The arm R forms a guide for placing the covers. The pins 1" and r prevent the disk from turning too far in either direc tion.

The plate R is adjusted lengthwise according to the length of the pamphlet.

The machine may be run faster or slower, according to the dexterity of the operator in placing the covers and removing the finished work.

The portion of the table where the pulley H is secured may be extended laterally any de sired distance to give a long belt, in which case two or more blocks, K, may be placed in position on the belt, so that while one set of pamphlets are being fed to the rollers another set may be arranged between two blocks K. When the forward block is near the roller D, it is removed and placed at the rear, and when a block is thus removed two or three pamphlets (more or less) may be placed in position to fill the gap caused by the removal of the block, and in this manner the machine would be made to operate continuously.
